Abstract
The utility model discloses a kind of heavy-metal contaminated soil processing systems, vibrating screen two that the vibrating screen one that is connected including sorting, dryer and dryer by belt conveyor, the double-roll crusher being connect by belt conveyor with vibrating screen one and double-roll crusher are connected by belt conveyor sorts system and solidification landfill system by the magnetization that belt conveyor is connect respectively with vibrating screen two, and the magnetization sorts system and also connect with solidification landfill system by belt conveyor.The various heavy in soil can be effectively removed, can get a large amount of purification soils in the case where not using water, and entire treatment process does not generate polluted source, process is simple, at low cost, high treating effect, has preferable Social benefit and economic benefit.
Description
Technical field
The utility model relates to heavy-metal contaminated soil processing technology field, specifically a kind of heavy-metal contaminated soil processing
System.
Background technique
In mining mineral resource, especially metallic mineral resources recovery process, barren rock mine tailings select smelting waste water, exhaust gas floating
Heavy metal element in dirt is all the primary pollution source of environment of mining area, leads to surrounding soil by pollution irrigation, atmospheric falling dust etc.
Middle content of beary metal increases, so that soil, surface water, underground water be made to be contaminated.
Currently, having the characteristic more using the smaller soil particle polluter adhesion amount of partial size in soil, using a large amount of
Water make the Soil slurry of heavy metal pollution, then carry out wet classification processing and remove fine product.But the method is deposited
The problem of be: sewage treatment step caused by sliming and for handling the dehydration cost of residue it is larger；It is another to ask
Topic after removing bulky grain soil, can not be generated recycling if in contaminated soil in the case where polluter too high levels
Clean earth.
In addition, there is technology to propose to add iron powder adsorption polluter in contaminated soil, then will be adsorbed by magnetic separator dirty
The iron powder for contaminating substance, which recycles, to be removed, thus the method for being purified soil.The method can remove stripping property polluter, still
The method is wet processed, needs a large amount of water to carry out sliming, and dehydration equipment is needed to be dehydrated, at high cost, in addition magnetic
The soil containing polluter selected is also without carrying out subsequent processing.
Summary of the invention
The purpose of this utility model is to provide a kind of heavy-metal contaminated soil processing systems, to solve above-mentioned background technique
Problem.
The technical solution of the utility model is achieved in that
A kind of heavy-metal contaminated soil processing system, including sorting, dryer, connect by belt conveyor with dryer
Vibrating screen one, connect by belt conveyor with vibrating screen one double-roll crusher, with double-roll crusher pass through Belt Conveying
The vibrating screen two of machine connection sorts system and solidification landfill system by the magnetization that belt conveyor is connect respectively with vibrating screen two
System, the magnetization sort system and are also connect with solidification landfill system by belt conveyor.
Further, it includes iron powder adding device and dry-type magnetic extractor that the magnetization, which sorts system,.
Further, the solidification landfill system includes curing agent adding set and landfill equipment.
The utility model has the following beneficial effects:
The utility model can effectively remove the various heavy in soil, can get in the case where not using water a large amount of
Purification soil, and entire treatment process does not generate polluted source, process is simple, at low cost, high treating effect, has preferable society
It can benefit and economic benefit.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it is therefore apparent that the accompanying drawings in the following description is only
Some embodiments of the utility model, for those of ordinary skill in the art, without creative efforts,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of heavy-metal contaminated soil processing system flow diagram of the utility model.
1- is sorted in figure, 2- dryer, 3- vibrating screen one, 4- double-roll crusher, 5- vibrating screen two, and 6- magnetization, which sorts, is
System, 7- solidify landfill system.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described ground embodiment is only the utility model a part of the embodiment, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, a kind of heavy-metal contaminated soil processing system, including sort 1, dryer 2, pass through with dryer 2
The vibrating screen 1 of belt conveyor connection, the double-roll crusher 4 connect by belt conveyor with vibrating screen 1 and double roller are broken
Vibrating screen 25 that broken machine 4 is connected by belt conveyor is selected by the magnetization that belt conveyor is connect respectively with vibrating screen 25
Other system 6 and solidification landfill system 7, the magnetization sort system 6 and are also connect with solidification landfill system 7 by belt conveyor.
The heavy-metal contaminated soil processing system processing method are as follows:
Then heavy-metal contaminated soil is given by sorting the sundries such as 1 removal waddy, weeds, plastics by belt conveyor
Dryer 2 is dried, and soil gives vibrating screen 1 by belt conveyor and carries out the dry classification ,+2mm being classified out after drying
Soil is purification soil on sieve, and -2mm soil is given double-roll crusher 4 by belt conveyor and is crushed, double-roll crusher 4
Ore discharge gives vibrating screen 25 by belt conveyor and carries out dry classification, is classified out+0.2mm soil and -0.2mm soil ,+0.2mm
Soil gives magnetization by belt conveyor and sorts system 6, obtain non-magnetic purification soil and magnetic object soil, -0.2mm soil
Solidification landfill system 7 is given by belt conveyor with magnetic object soil.
It is that a certain amount of chitosan magnetic is added in+0.2mm soil to stir evenly that the magnetization, which sorts system 6, then
Carry out dry type magnetic separation by dry-type magnetic extractor, obtain non-magnetic purification soil and magnetic object soil.
The solidification landfill system be a certain amount of curing agent is added to -0.2mm soil and magnetic in object soil stirring it is equal
It is even, then filled by filling equipment.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
